। ॥ १९७ ॥
In plain words
'Vidyā and avidyā' — the wise have taken that joint saying to speak of right action and upāsanā. Not of Self-knowledge and action. Not anywhere.
Close to the Sanskrit
'Vidyā and avidyā' — thus this joint statement has been made serviceable by the good with regard to right action and meditative worship, but not anywhere with regard to Self-knowledge and action.
